"ISIL's advance has highlighted all that has been wrong with the Iraqi government's Sunni strategy, which sacrificed political reforms in the interest of fighting 'terrorism' – a term it has used for all forms of Sunni violence but not for Shiite equivalents. This strategy enhanced polarisation and prepared the ground for the successful jihadi push in the north. International actors collectively failed to exert the necessary pressure on the Iraqi government to change its policy. Despite their recent conquests, jihadis are not on the verge of storming Baghdad. Nor is an all-out civil war inevitable; it could, however, be triggered by a disproportionate Iraqi Shiite and Iranian response that would cause Sunni ranks to close around the jihadis," writes the International Crisis Group.

"The question is how Obama should sequence his policy now. If he holds off on providing more military assistance while he waits for the Iraqis to negotiate such a political compact, the centrifugal forces that are already tearing Iraq apart will gain in strength. If on the other hand, Obama provides military assistance without fundamental political reform, he may only strengthen Maliki and reinforce a dangerous perception that the United States is siding with Shia over Sunni in a sectarian battle that has regional proportions….Nevertheless, President Obama and his team should opt for the more difficult path and decide to supply more military assistance without waiting to see political reforms fully enacted," writes CFR's Meghan L. O'Sullivan in Politico Magazine.

"Some have suggested that more sustained U.S. mentoring and advising—a residual force after the main withdrawal—could have averted the current catastrophe by making the Iraqi Army more competent and less partisan. But such notions vastly overstate U.S. leverage and influence. It's important to understand the limits of U.S. assistance: It can help build security institutions, but it cannot shape how those institutions are commandeered for personal, political or communal aims. Nor can it substitute for a government seen as reasonably equitable and legitimate," write Sarah Chayes and Frederic Wehrey for Politico Magazine.
